IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 36,787, datedOctoherfls 1862.

.To all whom it may concern.-

Be it known that I, JOHN LEES, of the city and county of Racine, in theState of Wisconsin, have invented a new and useful Improvement inGhurns; and I do hereby declare that the following is a full and exactdescription thereof. reference being had to the accompanying drawings,and to the letters and ligures of reference thereon marked.

In constructing my churn I use a rectangular box, No. 4, of suitablesize, and having its bottom curved to correspond to the swing of. thedashers. t

a is a support placed on the co er of the churn-box and at ,the centerlengthwise, and serves as the bearing for the dashers, which are pivotedat c.

b b are the support or bearings of the driving-Wheel, (marked No. 1,)which has its axis at d.

No. 3 No. 3 are connecting-rods made of thin slips of wood or metal, andpivoted at e to the pinion or crank. The other ends oft-heseconnecting-rods are pivoted, one atf, andthe other atf, to the dashers.(Marked No. 2.)

g are perforated dashers-blades of a length corresponding to the widthof the churn box.

In the operation of my invention, the churn being in the position asindicated in the drawings, it is filled with cream and the lid issecured. Motionis then communicated to the crank, which as it revolvesalternately flexes and unfi'exes the joint formed at e by theconnecting-rods, which in "turn flex and unflex the simila'rjoint formedat c by the dashers, thus making the dashers approach and recede fromeach other with any desired degree of rapidity. Each dasher has a swingfrom a point nearly vertically beneath the point 0 to the extreme end ofthe box. The perforated dasher-blades approach each other without quitetouching, and then recede to their respective ends of the box and thenreapproach at the next revolution of the crank. By this double change ofdirection and the squeezing (as it were) of the cream between thedasher-blades, I am enabled to agitate the cream in the most thoroughlyefifective manner.

The extreme simplicity of' construction and effectiveness of myinvention, are such as to greatly enhance its usefulness and recommendit to the use of butter-makers.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isr The construction and arrangementof the dashers No. 2 No. 2, connectingrods No. 3 No. 3, attached todriving-wheel No. 1, the whole constructed and operating substantiallyas hereinbefore set forth.
